One wrong communication choice… and your entire system becomes slow, unstable, or even crashes.

Most developers don’t realize how important transport layers are in microservices — until it’s too late.

In this video, you’ll learn the core differences between TCP, Redis, and gRPC and exactly when to use each one in real-world systems.

This is a must-know concept for backend developers and system design interviews.

In This Video, You’ll Learn:
What are Transport Layers in Microservices
TCP (Default & Simple Communication)
Redis (Pub/Sub Messaging System)
gRPC (High-Performance Communication)
TCP vs Redis vs gRPC (Clear Comparison)
When to Use What (Real-world Scenarios)
Common Mistakes Developers Make

Why This Video Matters:
Choosing the wrong communication method can lead to:
Slow performance
System bottlenecks
Poor scalability

This video will help you make architect-level decisions.

Who Should Watch:
* Backend Developers
* NestJS Developers
* Microservices Learners
* System Design Interview Preparation

Important:
There is NO one-size-fits-all solution.
In this video, you’ll learn how to choose the right tool for the right problem.
